33. Detect Circular Pattern Match

#include <stdio.h>
#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target)
{
    uint16_t rotated;

    for (int i = 0; i < 16; i++)
    {
        rotated = (reg >> i) | (reg << (16 - i));
        if (rotated == target)
            return 1;
    }
    return 0;
}

int main()
{
    uint16_t reg, target;
    scanf("%hu %hu", &reg, &target);
    printf("%hhu", is_circular_match(reg, target));
    return 0;
}
